=== Octal Number System: ===
 
* Octal number system has only eight digit from 0 to 7.
* Every number (value) represents with 0,1,2,3,4,5,,6,7 in the number system.
* The base of octal number system is 8 ,because it has only 8 digits.
 
=== Hexadecimal Number System: ===
 
* Hexadecimal number system has 16 alphanumeric value from 0 to 9 and A to F.
* Every number (value) represents with 0,1,2,3,4,5,6,7,8,9,,A,B,C,D,E and F in this number system.
* The base of hexadecimal number system is 16, because it has 16 alphanumeric value.
* Here A is 10 , B is 11, C is 12 , D is 13 ,E is 14 and F is 15.
 
'''Octal to decimal conversion:'''

Octal Number System:
'''Task 1:'''
Octal number system has only eight digit from 0 to 7.
Every number (value) represents with 0,1,2,3,4,5,,6,7 in the number system.
The base of octal number system is 8 ,because it has only 8 digits.


Hexadecimal Number System:
'''Task 2:'''
Hexadecimal number system has 16 alphanumeric value from 0 to 9 and A to F.
Every number (value) represents with 0,1,2,3,4,5,6,7,8,9,,A,B,C,D,E and F in this number system.
The base of hexadecimal number system is 16, because it has 16 alphanumeric value.
Here A is 10 , B is 11, C is 12 , D is 13 ,E is 14 and F is 15.


Octal to decimal conversion:
'''Task 3:'''
Explain the process of converting an octal number to its binary equivalent using a step-by-step method.
write a each step of conversion process in whiteboard and provides basic example.
Example No 1:
Example No 2:


Hexadecimal to octal Conversion:
* Encourage to the student to  ask the question if they have any problem in any step.
Explain how to convert a hexadecimal number to its binary equivalent and then to octal.
 
Work through examples and problems on the board, students should involve  in this process.
